HEEL OF BOOTS AND SHOES.

Specification forming part of Letters Patent No..43,024- dated June 7, 1864.

To all whom it may concern.-

Be it known that I, O. H. HELMs, of Poughkeepsie, in the county of Dutchess and State of New York, have invented a new and Improved Machine for Trimming the Heels of Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is a vertical section of my invention, taken in the line w m, Fig. 2; Fig. 2, a vertical section of the same, taken in the line y 3 Fig. 1; Fig. 3, a detached view of agage pertaining to the same.

Similar letters of reference indicate corresponding parts in'the several figures.

This invention consists in the employment or use of a rotary cutter-wheel provided with a guard at each'end and having cutters applied to it and fitted in throats in such a mannor that the heels of boots and shoes may be trimmed with the greatest facility and very expeditiously, and a free escape allowed for the shavings, so as to effectually prevent the choking or. clogging of the cutter-wheel.

To enable those skilled in the m to fully understancband construct my invention, I will proceed to describe it.

A represents a framing, which may be constructed in any suitable way to support the working parts of the machine and B is a horizontal shaft, which works in suitable bearin gs, a, on said framing, and has a cutterwheel, 0, at one end of it. This wheel 0 has a beveled periphery corresponding to the form designed to be given the heel to be trimmed,

and prevent the choking or clogging 'of the wheel. The edges of the cutters D are ground longitudinally to correspond in form to a transverse section of the periphery of the wheel 0, and they are set a trifle beyond said -leave a projecting rim, h, above 9.

periphery according to the depth of cut desired, the cutters being secured in position by screws 0.

E represents a guard, which is attached to the framing, and is ofcircular form at its upper part and providedwith a lateral flange, d, which projects 'a trifle over the inner edge of the cutter-wheel O, as shown clearly in Fig. 1.

F represents a guard, which is similar to E, but is removable or detachable, said guard being of circular form and having a radial slot, e, made in it, extending from its center outward. (See Fig.3.) The guard F is fitted on an arbor, f, in the framing, and it is provided at its upper part and inner side with a lateral semicircular flange, g, which projects over the outer edge of the wheel C, said flange being a portion of a circle rather smaller in diameter than'the guard, so as to (See Fig. 1. The flange g also projects from a semicircular portion, t, at the inner side. of the guard, which admits of aspace, j, being'below it for the shavings to drop through from the throats b b. The heel G of the boot or shoe and keeps turning the heel on the cutterwheel 0, the intermediate layers of the heel being cut away until the lower layer, It, comes in contact with the flange g, and the counter m of the boot or shoe comes in contact with the flange d of the guard F, when the work is completed. The rim h of the guard F serves as a guide for the heel to keep the same in proper position over the cutter-wheel.

By this device the heels of boots and shoes may be trimmed very expeditiously, with great facility, and in a perfect manner.

Havingthns described my invention, whatI arranged as shot m; in connection with the claim as new, and desire to secure by Letters space j between the guard F-and the outer Patent, isside of the cutter-wheel O, to admit of the free 1.
